Dense shaped refractory products — Determination of cold compressive strength — Part 1: Referee test without packing
Scope:
This document specifies a method for determination of the cold compressive strength of dense shaped refractory products.
Shaped refractories are those which have fixed geometry and dimensions when delivered to the user. This document is accordingly applicable to standard shape refractory bricks, but also special shapes refractory products and pre-cast products.

Fine ceramics (advanced ceramics, advanced technical ceramics) — Test method for fracture resistance of monolithic ceramics at room temperature by indentation fracture (IF) method
Scope:
This document specifies a test method for determination of the fracture resistance of monolithic ceramics at room temperature using the indentation fracture (IF) method.
This document is applicable to dense monolithic ceramics and whisker- or particulate-reinforced ceramics which are regarded as macroscopically homogeneous. This document is not applicable to monolithic silicon nitride ceramics for bearing balls and continuous-fibre-reinforced ceramics composites.
This document is applicable for material development, material comparison, quality assurance, characterization and reliability data generation.
Indentation fracture resistance, KI,IFR, as defined in this document is not to be equated with fracture toughness determined using other test methods such as KIsc and KIpb.
NOTE KI,IFR is an estimate of a material’s resistance to cracking as introduced by an indenter and has correlations with wear resistance and rolling contact fatigue performance as well as machining processes, since these properties are governed by the resistance to crack extension in localized damage areas.[1]-[3] By contrast, fracture toughness properties KIsc and KIpb are intrinsic properties of a material and are relevant to macroscopic and catastrophic fracture events with long cracks rather than those phenomena caused by microscopic and successive damage accumulation associated with short cracks.

Glass in building - Folio interlayers for the manufacturing of laminated glass
Scope:
This document specifies the composition, tolerances and characteristics, i.e. mechanical, acoustic, optical and thermal properties, of folio interlayers for the manufacturing of laminated glass and laminated safety glass for use in buildings and construction works and it defines their general quality criteria.
This document does not apply to interlayers for laminated glass which are achieved by pouring the interlayer material in liquid state on or between the plies of glass or plastic glazing sheet material generally followed by drying or by chemical or ultraviolet curing.

Dense and insulating shaped refractory products — Determination of modulus of rupture at ambient temperature
Scope:
This document specifies a method for the determination of the modulus of rupture of dense and insulating shaped refractory products at ambient temperature, under conditions of a constant rate of increase of stress.
Shaped refractories are those which have fixed geometry and dimensions when delivered to the user. This document is accordingly applicable to standard shape refractory bricks, but also special shapes refractory products and pre-cast products.
This document is also applicable to unshaped refractories (see ISO 1927-6) after preparation of test specimens according to ISO 1927-5.

Scope:
This document describes a test method that covers the determination of fracture resistance of monolithic ceramics at room temperature by the indentation fracture (IF) method.
This document is intended for use with dense monolithic ceramics and whisker- or particulate-reinforced ceramics which are regarded as macroscopically homogeneous. It does not include monolithic silicon nitride ceramics for bearing balls and continuous-fibre-reinforced ceramics composites.

NOTE KI,IFR is an estimate of a material's resistance to cracking as introduced by an indenter and has correlations with wear resistance and rolling contact fatigue performance as well as machining processes, since these properties are governed by the resistance to crack extension in localized damage areas[1]-[3]. By contrast, fracture toughness properties KIsc and KIpb are intrinsic properties of a material and are relevant to macroscopic and catastrophic fracture events with long cracks rather than those phenomena caused by microscopic and successive damage accumulation associated with short cracks.
